+      summary: "Measures the spatial autocorrelation of the inferred pseudotime across the spatial coordinates of the cells/spots."
+      description: |
+        Computes Moran's I statistic for the inferred pseudotime, using a k-nearest-neighbour
+        graph built on the spatial coordinates (`obsm['X_spatial']`) of the cells/spots.
+
+        Moran's I quantifies how similar the pseudotime values of spatially neighbouring
+        cells/spots are. Values close to 1 indicate a spatially smooth trajectory in which
+        neighbouring cells receive similar pseudotime values, values around 0 indicate a
+        spatially random assignment, and negative values indicate that neighbouring cells
+        receive dissimilar pseudotime values.
+
+        Note that this metric evaluates the spatial coherence of the prediction only and does
+        not compare it against the ground-truth pseudotime; a spatially smooth but incorrect
+        ordering can still score highly.
